Generic health status questionnaire
Perceived health status was measured according to the first
part of the NHP, developed in the UK in the 1970s for use in
population surveys.17 This self-administered instrument,
validated in a French version,18 consists of 38 items pertaining to how people feel or operate in their daily life. The
items cover the following six dimensions: physical mobility,
pain, sleep, energy, social isolation and emotional reactions.
Patients were asked whether or not each item applied to them. Positive answers were given the appropriate weight, resulting in score range from 0 to 100 for each dimension. Dimension scores were only calculated if no data were missing on the dimension concerned. Higher scores correspond to a lower perceived health status.
